Technical Field
The utility model belongs to the technical field of plasma spray guns, and particularly relates to a plasma rotating spray gun.
Background
The plasma surface treatment technology is characterized by that it utilizes high-voltage high-frequency discharge to make the energy of particles in the plasma generally be about several to several tens of electron volts, and greater than the binding bond energy of polymer material (several to more than ten electron volts), and can completely break the chemical bond of organic macromolecular to form new bond, and the electrons have higher energy, and can break the chemical bond of surface molecule of material, raise chemical reaction activity of particles, and can raise surface tension, fine-clean, remove static electricity and activate surface.
The discharge part of a plasma electrode in the existing plasma spray gun is pointed, the area of the pointed discharge part is small, the area of a discharge position is small due to long-time pointed discharge, so that the temperature is continuously high, the plasma electrode is easy to damage, and the service life of the plasma electrode can be only about 1 year or even shorter.
SUMMERY OF THE UTILITY MODEL
Accordingly, the present invention is directed to a plasma spin gun that solves the above problems.
The utility model provides a plasma rotating spray gun, includes the rifle body, is located the shower nozzle of rifle body one end, fixes internal ceramic base of rifle and being located the rifle is internal and install plasma electrode on the ceramic base, plasma electrode is from keeping away from ceramic base one end orientation the shower nozzle sets up and is spherical structure, spherical structure is close to the inside wall of the rifle body.
Further, the spray head is in threaded connection with the gun body.
Further, the plasma electrode is in threaded connection with the ceramic base.
Compared with the prior art, the plasma rotating spray gun provided by the utility model has the advantages that the discharge area of the spherical structure of the plasma electrode is larger than the tip discharge area of the plasma electrode, the discharge position does not discharge at the same position of the spherical structure, and the discharge can be carried out at a plurality of different positions of the spherical structure, so that the spherical structure of the plasma electrode does not continuously heat up at the same position, the plasma electrode is not easily damaged by high temperature, and the service life of the plasma electrode is prolonged; meanwhile, as the spherical structure is close to the inner side wall of the gun body, the discharging distance during discharging is reduced, and the discharging is quicker.

Detailed Description
Specific examples of the present invention will be described in further detail below. It should be understood that the description herein of embodiments of the utility model is not intended to limit the scope of the utility model.
Fig. 1 to 2 are schematic structural diagrams of a plasma rotating torch according to the present invention. The utility model provides a plasma rotating spray gun, includes the rifle body 10, is located the shower nozzle 20 of rifle body 10 one end, fixes ceramic base 30 in the rifle body 10 and be located in the rifle body 10 and install plasma electrode 40 on the ceramic base 30, plasma electrode 40 is from keeping away from ceramic base 30 one end orientation shower nozzle 20 sets up and is spherical structure 41, spherical structure 41 is close to the inside wall of rifle body 10.
The gun body 10 is connected with a host through a connecting pipe from one end far away from the spray head 20;
when the plasma electrode device works, the host machine drives the plasma electrode 40 to discharge, and because the discharge area of the spherical structure 41 of the plasma electrode 40 is larger than the tip discharge area of the plasma electrode 40, the discharge position does not discharge at the same position of the spherical structure 41, and the discharge can be carried out at a plurality of different positions of the spherical structure 41, the spherical structure 41 of the plasma electrode 40 does not continuously heat up at the same position, so that the plasma electrode 40 is not easily damaged by high temperature, and the service life of the plasma electrode 40 is prolonged; meanwhile, as the spherical structure 41 is close to the inner side wall of the gun body 10, the discharge distance during discharge is reduced, so that the discharge is quicker.
It should be noted that, after the spherical structure 41 of the plasma electrode 40 is matched with the inner side wall of the gun body 10 for discharging, the main machine drives the blower to blow air, and the air is conveyed into the gun body 10 through the connecting pipe, so as to blow out the discharged free ions for spraying the objects.
The spray head 20 is in threaded connection with the gun body 10. The spray head 20 can be replaced according to actual needs, and is convenient and quick to install.
The plasma electrode 40 is screwed to the ceramic susceptor 30. The plasma electrode 40 has a certain service life, and after the plasma electrode 40 is damaged, the damaged plasma electrode 40 can be detached, and a new plasma electrode 40 is installed again, so that the installation is convenient and quick, and the practicability is high.
Compared with the prior art, the plasma rotating spray gun provided by the utility model has the advantages that the discharge area of the spherical structure 41 of the plasma electrode 40 is larger than the tip discharge area of the plasma electrode 40, the discharge position does not discharge at the same position of the spherical structure 41, and the discharge can be carried out at a plurality of different positions of the spherical structure 41, so that the spherical structure 41 of the plasma electrode 40 does not continuously heat up at the same position, further the plasma electrode 40 is not easily damaged by high temperature, and the service life of the plasma electrode 40 is prolonged; meanwhile, as the spherical structure 41 is close to the inner side wall of the gun body 10, the discharge distance during discharge is reduced, so that the discharge is quicker.
